The range carries a continuous rating of 150A DC and 130A AC, with layouts that use four 1\/4\"-20 studs or a mix of #8-32 screw terminals and two 1\/4\"-20 studs.\u003c\/p\u003e\u003cp\u003eThis busbar is a practical fit for electrical panels, battery switch areas, charger and inverter installations, and other places where several circuits need a shared connection point. The tin-plated copper bus helps maintain conductivity in marine electrical work, while the UL 94-V0 rated glass-reinforced thermoplastic base gives the terminals a stable mounting platform.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eRated for 150A continuous DC service and 130A continuous AC service.\u003c\/li\u003e\n\u003cli\u003eSupports systems up to 48V DC or 300V AC.\u003c\/li\u003e\n\u003cli\u003eAvailable in 4-stud, 10-gang, and 20-gang layouts to match different circuit counts.\u003c\/li\u003e\n\u003cli\u003eTerminal options include 1\/4\"-20 studs and #8-32 screw terminals, depending on the selected layout.\u003c\/li\u003e\n\u003cli\u003eTin-plated CDA 110 copper bus material supports dependable current distribution in onboard electrical systems.\u003c\/li\u003e\n\u003cli\u003eUL 94-V0 rated glass-reinforced thermoplastic base helps keep the assembly secure inside panels, lockers, and equipment spaces.\u003c\/li\u003e\n\u003cli\u003eSelect configurations include a clear polycarbonate cover for added protection over the connection area.\u003c\/li\u003e\n\u003cli\u003eStud terminals are insert-molded stainless steel for high-torque electrical contact without a separate securing nut.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis Common 150A BusBar range varies by terminal layout and cover configuration. The layout options include four-stud versions for larger ring-terminal connections, 10-gang versions for moderate circuit grouping, and 20-gang versions for panels or negative return points with more branch circuits.\u003c\/p\u003e\u003cp\u003eSome versions include a clear polycarbonate cover, while others are supplied without a cover for installations where a separate cover, enclosure, or panel arrangement is being used. Across the range, the busbar rating remains 150A DC and 130A AC, with maximum system voltage of 48V DC or 300V AC.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eInstall the busbar on a flat, secure surface where the terminals are protected from accidental contact and where cable runs can be kept orderly. Covered versions are useful in exposed service areas inside the boat, while uncovered versions can suit protected enclosures or panel interiors where the installation already provides shielding.\u003c\/p\u003e\u003cp\u003eUse properly sized marine cable, matched ring terminals, and circuit protection appropriate for the connected loads. The screw terminal torque is 15 in-lb, and the stud torque is 60 in-lb, which helps with consistent installation and repeatable contact pressure during panel work or system upgrades.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis busbar is well suited for builders and owners organizing DC distribution, negative return circuits, or AC grounding points in compact marine electrical spaces. It is a good match for refits, new panel builds, electronics additions, and service work where multiple conductors need a common, clearly organized termination point.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"4 Studs \/ No Cover","offer_id":52581892587701,"sku":"QBP413019-V0","price":32.99,"currency_code":"USD","in_stock":true},{"title":"10-Gang Screws + 2 Studs \/ No Cover","offer_id":52581892620469,"sku":"QBP413019-V3","price":24.99,"currency_code":"USD","in_stock":true},{"title":"10-Gang Screws + 2 Studs \/ With Cover","offer_id":52581892653237,"sku":"QBP412891-V8","price":29.99,"currency_code":"USD","in_stock":true},{"title":"20-Gang Screws + 2 Studs \/ No Cover","offer_id":52581892686005,"sku":"QBP413019-V4","price":39.99,"currency_code":"USD","in_stock":true},{"title":"4 Studs \/ With Cover","offer_id":52581892718773,"sku":"QBP413019-V5","price":38.99,"currency_code":"USD","in_stock":true},{"title":"20-Gang Screws + 2 Studs \/ With Cover","offer_id":52581892751541,"sku":"QBP412891-V6","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334137_qbp413019.webp?v=1780201322","url":"https:\/\/www.qualityboatparts.com\/products\/qbp413019","provider":"Quality Boat Parts","version":"1.0","type":"link"}
